Before you switch
No. Sent charges its platform fee once per active contact, so the saving grows with how often you message the same people. The sample above sends three messages to each contact in a billing period. If most of your contacts hear from you only once, paying per message part can cost less. The estimator on the pricing page works it out for your own mix.
On Sent, each customer you send for is a Sender Profile inside your own organization, and you send on their behalf by passing that profile’s ID. On Telnyx, each customer is a managed account, created through the API after manager-account approval, with its own messaging resources configured.
Yes. Sender registration, such as A2P 10DLC in the US, WhatsApp business verification and template approvals, is decided by the carriers and by Meta, whichever platform you send through. We run the submissions with you and tell you where each one stands, but the review itself belongs to them.
Start with one flow, such as order updates or verification codes. Route a share of that traffic through Sent, compare delivery against Telnyx on the same messages, and move the rest once the numbers agree. Your current setup keeps running the whole time.
